It is named after Sisir Kumar Mitra, who was an Indian physicist and Padma Bhushan award recipient known for his pioneering work in the field of ionosphere and radiophysics.

[1] This is a heavily eroded formation with an outer rim that has been damaged by subsequent impacts.

Attached to the exterior along the southeast is the satellite crater Mitra J.

Within the interior, a smaller crater occupies the southwestern part of the floor, and a small, cup-shaped crater lies across the northeast rim of this formation and very close to the midpoint of Mitra.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Mitra.
